Parking sensor problem

[bartucz91]

Hi guys,
I got a parking sensor problem with my POLO. The problem is: If i put it in reverse, after 2 seconds its beep-ing continue. Its a different tone than when something is really close. (and the sensor is not dirty). We managed to read out with the software, there is a problem with the mid-right sensor. It says: "01547 Sensor for parking aid: Rear Mid-Ridght (G205) 30-00 -Open or short to Plus". We changed the sensor with the another one, and restarted the car and the software, and the problem jumped to the new place. So i would say the sensor is broken and the cabeling is still good. The sensor is 7H0919275C.
And my question is, wich brand do you guys are offering ? I see this product from 15 till 100 euro. Is there any difference?
And my other question is, its comming in black, but i have a grey/green auto. How can i find the exact paint for it? Or shall i look for a same colored auto at the junkjard and buy the sensor for some euros?

Thanks for the help,
Csaba
